“…In addition, because silk fabric has a fairly low permittivity value of 1.75, the gain value obtained is also higher. This is because the permittivity value is inversely proportional to the gain value, so the lower the permittivity value, the greater the gain value obtained [13]. Another factor affecting the high-value gain is the thickness of the substrate, where a silk substrate has a higher thickness than cotton.…”

“…Another factor affecting the high-value gain is the thickness of the substrate, where a silk substrate has a higher thickness than cotton. Because the increase in the thickness of the substrate is directly proportional to the increase in the value of the gain, it can be ascertained that the value of the obtained gain is also higher [12], [13].…”

Textile antennas are currently being researched and developed so that they can be integrated into clothing. In this paper, two textile antennas with cotton and silk substrate are presented. The antennas operate at GPS L1 frequency, which is 1.575 GHz. This paper discusses the effect of antenna parameters on free space and on-body conditions, and the effect of antenna bending. Based on simulation and measurement results, the parameter values obtained indicate that the antenna can operate properly at a frequency of 1.575 GHz and is safe to use on the body.

The paper presents a stub microstrip patch antenna for sub 6 GHz, that is used in 5G applications. The background of each part of the theory and the rules of the design of the antenna are described. 5G technology and its advantages are mentioned in this paper. Also, the reason why the microstrip patch antenna is used in this project, and what effect it has on the results, is described. The physical structure can be different, and it can behave differently. This paper uses a rectangular shape. The antenna also has tunning stub, and slits and slots, which are discussed in the paper. The antenna is simulated and analyzed, using Sonnet Suites Software [1]. The changes that were analyzed are geometry, dielectric thickness, and dielectric constant. The substrate that is used for designing the antenna is an FR-4. The antenna operates at 5.5 GHz with S11 of -12.605 dB, E-Theta of 4.646 dB, and E-Phi of -7.508 dB. These values are suitable for 5G applications.

“…The antenna is a necessary wireless communication device for receiving and transmitting relevant signals at specific frequencies [7]. Various wearable antennas with flexible properties exist in the literature, using a range of polymer-and paper-based substrates with permittivity values often ranging from 1.5 to 13 [8,9]. Textile materials, made of fibrous polymer materials, are ubiquitous in our daily lives, and they offer a light and flexible substrate for wearable systems and devices.…”

Recent advancements in printing technologies have greatly improved the fabrication efficiency of flexible and wearable electronics. Electronic textiles (E-textiles) garner particular interest because of their innate and desirable properties (i.e., conformability, breathability, fabric hand), which make them the ideal platform for creating wireless body area networks (WBANs) for wearable healthcare applications. However, current WBANs are limited in use due to a lack of flexible antennas that can provide effective wireless communication and data transfer. In this work, we detail a novel fabrication process for flexible textile-based multifunctional antennas with enhanced dielectric properties. Our fabrication process relies on direct-write printing of a dielectric ink consisting of ultraviolet (UV)-curable acrylates and urethane as well as 4 wt.% 200 nm barium titanate (BT) nanoparticles to enhance the dielectric properties of the naturally porous textile architecture. By controlling the spray-coating process parameters of BT dielectric ink on knit fabrics, the dielectric constant is enhanced from 1.43 to 1.61, while preserving the flexibility and air permeability of the fabric. The novel combination textile substrate shows great flexibility, as only 2 N is required for a 30 mm deformation. The final textile antenna is multifunctional in the sense that it is capable of operating in a full-duplex mode while presenting a relatively high gain of 9.12 dB at 2.3 GHz and a bandwidth of 79 MHz (2.260–2.339 GHz) for each port. Our proposed manufacturing process shows the potential to simplify the assembly of traditionally complex E-textile systems.
